Description:

BACKGROUND

[0001] 1. Field

[0002] Embodiments of the present invention relate to an apparatus for
stabilizing a kayak or other small water vessel so that a person can more
easily get into and out of the vessel.

[0003] 2. Related Art

[0004] Getting into and out of kayaks and other small water vessels from a
dock can be challenging for a number of reasons. First, wind or waves may
cause the vessel to float in a direction away from the dock. Second, the
user may tip the vessel over or fall out of the vessel while lowering
themselves into it. Accordingly, a user may need something to stabilize
themselves and/or the vessel as they get into and out of it.

[0005] Many different types of devices have been developed in an attempt
to alleviate these problems. For example, an overhead assist bar may be
mounted between two adjacent docks or sections of a single dock and may
be grasped by a user as the user gets into or out of a vessel. However,
this requires that the two docks or dock sections be built close enough
together that the overhead assist bar of a fixed size can extend
therebetween. Moreover, although such bars help a user steady him or
herself, they do not help stabilize the vessel itself.

[0006] Accordingly, there is a need for an improved apparatus that assists
a user while getting into and out of a water vessel.

SUMMARY

[0007] Embodiments of the present invention provide an apparatus that may
be mounted virtually anywhere on a dock, pier, or other structure
positioned over a body of water that allows a user to get into and out of
a small water vessel, such as a kayak, canoe, jet ski, wave runner, etc.
An embodiment of the apparatus may comprise a support structure fixedly
secured to a dock, pier, or other structure and a handrail pivotally
attached to the support structure. The support structure may comprise a
base fixedly secured to the dock or other structure and a support rail
extending vertically upward from the base.

[0008] The handrail may have a proximal end and a distal end. The proximal
end of the handrail may be pivotally attached to the support rail at a
point proximate to the base, so that the handrail may pivot between a
folded configuration in which the handrail is substantially parallel to
the support rail and an unfolded configuration in which the handrail is
substantially perpendicular to the support rail.

[0009] In another embodiment of the invention, the apparatus may further
comprise a vessel retaining arm pivotally attached to the distal end of
the handrail. The vessel retaining arm may be pivotable between a folded
configuration in which the vessel retaining arm is substantially parallel
to the handrail and an unfolded configuration in which the vessel
retaining arm is substantially perpendicular to the handrail. The
apparatus may also be configured such that a length of the handrail
and/or the vessel retaining arm may be adjusted via mechanical actuation.

[0010] This summary is provided to introduce a selection of concepts in a
simplified form that are further described below in the detailed
description. This summary is not intended to identify key features or
essential features of the claimed subject matter, nor is it intended to
be used to limit the scope of the claimed subject matter. Other aspects

[0023] As illustrated in FIGS. 1-7, embodiments of the present invention
provide an apparatus 10 attachable to a dock 12, pier, or other structure
that extends over a body of water 14. A user 16 may use the apparatus 10
to get into and out of a small water vessel 18, such as a kayak, as
illustrated in FIG. 1, a canoe, a wave runner, or a jet ski. The dock 12,
as referenced herein, may be any type of dock, pier, docking structure,
or any other structure positioned over the body of water 14. The
apparatus 10 broadly includes a support structure 20 attachable to the
dock 12, a handrail 22 pivotally attached to the support structure 20,
and a vessel retaining arm 24 pivotally attached to the handrail 22.

[0024] The support structure 20 may be any rigid part configured to attach
to and extend upward from the dock 12. Specifically, the support
structure 20 may comprise a base 30 configured to be fixedly secured to
the dock 12 and at least one support rail 26,28 extending substantially
vertically upward from the base 30. The support structure 20 may further
comprise one or more bracing elements 32 and/or a locking mechanism 34,
as later described herein.

[0025] Each support rail 26,28 may be rigid and elongated, comprising a
first end 36 and a second end 38 opposite the first end 36. The support
rail 26, 28 may be configured to extend upward, substantially
perpendicular to the dock 12. The first end 36 of each support rail 26,28
may be attached to, welded to, and/or integrally formed with the base 30.
The support rails 26,28 may have holes 40,42 formed therein or
therethrough, configured for pins or other devices to be slid
therethrough, as best illustrated in FIG. 2. For example, at least one of
the support rails 26,28 may have one or more locking holes 40 formed
therethrough, configured to allow a locking pin 44 to be slid
therethrough. Furthermore, at least one of the support rails 26,28 may
have a pivot hole 42 positioned and configured to allow a pivot pin 46 to
be slid therethrough. The locking pin 44 may secure the handrail 22 to
the support structure 20 in several different configurations, as later
described herein. The pivot pin 46 may extend through both the support
structure 20 and the handrail 22, such that the handrail 22 may pivot or
rotate about the pivot pin 46. However, in alternative embodiments of the
invention, the pivot pin 46 may be fixed to or integrally formed with at
least one of the support rails 26,28 and the pivot hole 42 may be
omitted.

[0026] In some embodiments of the invention, as illustrated in FIGS. 1, 5,
and 6, the support structure 20 may specifically comprise two support
rails 26,28 arranged parallel with each other with a space therebetween,
such that when the handrail 22 is pivoted toward the support structure
20, the handrail 22 rests between the two support rails 26,28 of the
support structure 20. The two support rails 26,28 may be solid throughout
or may be substantially hollow and have a square cross-section or any
desired cross-section. The two support rails 26,28 may be held parallel
with each other by their fixed attachment to the base 30 and/or by a
rigid strap 48 fixedly attached or integrally formed to each of the
support rails 26,28. For example, the rigid strap 48 may be fixed to the
support rails 26,28 at or proximate to the second end 38 of each.

[0027] The base 30, as illustrated in FIGS. 1, 5, 6, and 7, may be
configured to be bolted to or otherwise attached at or proximate to an
edge of the dock 12. However, any type of base or means of securing the
support structure 20 to the dock 12 may be used. The base 30 may be
secured to the dock 12 by mechanical fasteners 50, such as bolts, nails,
screws, or other mechanical fasteners. In some embodiments of the
invention, as illustrated in FIGS. 1 and 5, the base 30 may be an
elongated angle rail, which may comprise a first base portion 52
configured to lay on top of the dock 12 and a second base portion 54
extending at a substantially 90-degree angle from the first base portion
52. The first base portion 52 may be attached directly to a top surface
of the dock 12, such as by way of the mechanical fasteners 50.
Furthermore, the second base portion 54 may be configured to be attached
directly to a side of the dock 12, such as by way of the mechanical
fasteners 50. In some embodiments of the invention, the base 30 or
another component of the apparatus 10 may comprise a lanyard attachment
component (not shown) configured to allow a lanyard or rope fixed to the
water vessel 18 to attach to the lanyard attachment component, thereby
securing the water vessel 18 to the dock 12.

[0028] The bracing elements 32, as illustrated in FIGS. 1-2 and 5-7, may
extend between the base 30 and one or both of the support rails 26,28.
For example, the bracing elements 32 may be fixed to both the base 30 and
at least one of the support rails 26,28 at an angle greater than
0-degrees and less than 90-degrees, as illustrated in FIGS. 1 and 5. The
bracing elements 32 may be arranged in such a manner that the support
rail 26,28 is braced, relative to the base 30, against movement forward
and backwards as well as movement from side to side.

[0029] The locking mechanism 34, as illustrated in FIGS. 1-2 and 5-7, may
be any mechanism configured to temporarily fix the handrail 22 in a
configuration substantially perpendicular to the support rail or rails
26,28. For example, the locking mechanism 34 may be a rigid component
with at least one locking hole 56 formed therethrough and fixed in a
position relative to the base such that at least one corresponding
locking hole 58 formed into the handrail 22 may be aligned therewith, as
later described herein. The locking pin 44 may be configured to be
inserted through the locking hole 56 of the locking mechanism 34 and
through the locking hole 58 of the handrail 22 in order to prevent the
handrail 22 from pivoting relative to the support structure 20. In some
embodiments of the invention, the locking mechanism 34 may be fixed to
any elements of the support structure 20 and/or the dock 12 and may be
sized and shaped to impeded the handrail 22 from pivoting more than
90-degrees relative to the support rails 26,28.

[0030] The handrail 22, as illustrated in FIGS. 1-3 and 5-7, may comprise
one or more elongated rods 60,62 or any part configured to pivotally
attach to the support structure 20 and/or the dock 12 and to extend in a
direction away from the dock 12 over the body of water 14. Specifically,
the handrail 22 may be configured to extend over the water vessel 18 or
any vessel floating in the body of water 14. The handrail 22 may comprise
a proximal end 64 configured to be positioned at or nearest to the dock
12 and a distal end 66 opposite of the proximal end 64. The handrail 22
may pivot between a folded configuration generally parallel with the
support rail 26,28 and a unfolded configuration generally perpendicular
to the support rail 26,28.

[0031] The handrail 22 may have a number of holes formed therethrough, as
best illustrated in FIGS. 2 and 7. Specifically, one of the elongated
rods 60,62 of the handrail 22 may have at least one pivot hole 68 formed
therethrough and aligned with the pivot hole 42 or holes of the support
structure 20, such that the pivot pin 46 may extend through the pivot
holes 42,68 of both the support structure 20 and the handrail 22.
Furthermore, at least one of the elongated rods 60,62 of the handrail 22
may have the at least one locking hole 58 formed therethrough and
configured to align with the locking mechanism's hole(s) 56 while the
handrail is in the unfolded configuration and with the locking hole(s) 40
of the support rail(s) 26,28 while the handrail 22 is in its folded
configuration.

[0032] In some embodiments of the invention, as illustrated in FIG. 3, the
one or more elongated rods 60,62 of the handrail 22 may comprise a first
hollow rod 60 and a second hollow rod 62, wherein the second hollow rod
62 has a smaller cross-section than the first hollow rod 60 and is
slidable at least partially into and out of the first hollow rod 60. In
this embodiment of the invention, the pivot holes 68 and locking holes 58
of the handrail 22 may be formed through the first hollow rod 60.
Alternatively, the pivot holes 68 and locking holes 58 of the handrail 22
may be formed through the second hollow rod 62. The first and second
hollow rods 60,62 may each have a substantially square or circular
cross-section or any cross-sectional shape desired.

[0033] The first hollow rod 60 may have a plurality of length-adjustment
holes 70 formed therethrough and spaced at intervals along a length of
the first hollow rod 60. The second hollow rod 62 may comprise at least
one length-adjustment hole 72 formed therethrough and configured to align
with the length-adjustment holes 70 of the first hollow rod 60.
Additionally, the handrail 22 may also comprise a spring-biased mechanism
74 resting at least partially within the second hollow rod 62 and at
least partially extending through the length-adjustment hole 72 of the
second hollow rod 62, as illustrated in FIG. 3.

[0034] For example, the spring-biased mechanism 74 may have a spring
portion 76 having a first end 78 and a second end 80 and a tab portion 82
attached to or integral with the second end 80 of the spring portion 76.
The first end 78 of the spring portion 76 may or may not be fixed to a
surface within the second hollow rod 62. The tab portion 82 may extend
through the length-adjustment hole 72 of the second hollow rod 62 and at
least one of the length-adjustment holes 70 of the first hollow rod 60
when these length-adjustment holes 70,72 are aligned with each other.

[0035] When the tab portion 82 is pressed inward toward the spring portion
76, the first hollow rod 60 may be operable to be slid toward or away
from the support structure 20 of the apparatus 10 until another of the
length-adjustment holes 70 of the first hollow rod 60 aligns with the
length adjustment hole 72 of the second hollow rod 62, allowing the tab
portion 82 to spring out through the aligned length-adjustment holes
70,72. In alternative embodiments of the invention, not shown herein,
there may be aligned length-adjustment holes on two opposing sides of the
first hollow rod 60 and/or the second hollow rod 62 and there may be tab
portions 82 on each end 78,80 of the spring portion 76, such that
simultaneously squeezing both tab portions 82 toward the spring portion
76 is required to adjust the length of the handrail 22.

[0036] The handrail 22 may also comprise an attachment part 84, as
illustrated in FIGS. 1-7, fixed to or integrally formed with one of the
elongated rods 60,62 at or proximate to the distal end 66 of the handrail
22. For example, the attachment part 84 may be attached to the second
hollow rod 62 and may be substantially perpendicular to the second hollow
rod 62. The attachment part 84 may comprise at least one retaining arm
pivot hole 86 formed therethrough configured to receive a retaining arm
pivot pin 88 about which the vessel retaining arm 24 may pivot, as
illustrated in FIGS. 5-6. The attachment portion 84 may be also be
configured to prevent the vessel retaining arm 24 from pivoting greater
than substantially 90-degrees relative to the handrail 22.

[0037] In some alternative embodiments of the invention, the retaining arm
pivot hole 86 may extend through one of the elongated rods 60,62, such as
the second hollow rod 62, and the attachment part 84 may be omitted.
However, advantageously, the attachment part 84 allows for the vessel
retaining arm 24 to rest a distance apart from and substantially parallel
to the handrail 22 when the handrail 22 is in the folded configuration,
as illustrated in FIG. 6.

[0038] The vessel retaining arm 24, as illustrated in FIGS. 1-2 and 4-7,
may freely pivot relative to the distal end 66 and/or the attachment part
84 of the handrail 22 between a folded configuration and an unfolded
configuration. The vessel retaining arm 24 may remain substantially
vertical and substantially parallel to the support rails 26,28 as the
handrail 22 pivots between its folded and unfolded configurations. In its
unfolded configuration, the vessel retaining arm 24 rests at about a
90-degree angle relative to the handrail 22 and extends therefrom in a
direction toward the body of water 14. The vessel retaining arm 24 may
pivot about the retaining arm pivot pin 88 relative to the handrail 22.
The vessel retaining arm 24 may therefore also comprise at least one
pivot hole 90 formed therethrough and operable to receive the retaining
arm pivot pin 88.

[0039] As illustrated in FIG. 4, the vessel retaining arm 24 may comprise
a third hollow rod 92 and a fourth hollow rod 94 similar in construction
and operation to the first hollow rod 60 and the second hollow rod 62 of
the handrail 22. Specifically, the third and fourth hollow rods 92,94 may
be slidable relative to each other to mechanically lengthen or shorten
the vessel retaining arm 24. In one embodiment of the invention, as
illustrated in FIG. 4, the fourth hollow rod 94 may have a smaller
cross-section than the third hollow rod 92 and may slide into the third
hollow rod 92. Furthermore, the third hollow rod 92 may have the vessel
retaining arm's pivot hole 90 formed therethrough. Alternatively, the
vessel retaining arm's pivot hole 90 may be formed through the fourth
hollow rod 94. The third and fourth hollow rods 92,94 may each have a
substantially square or circular cross-section or any cross-sectional
shape desired.

[0040] The third hollow rod 92 may have a plurality of length-adjustment
holes 96 formed therethrough and spaced at intervals along a length of
the third hollow rod 92. The fourth hollow rod 94 may comprise at least
one length-adjustment hole 98 formed therethrough and configured to align
with the length-adjustment holes 96 of the third hollow rod 92.
Additionally, the vessel retaining arm 24 may also comprise a
spring-biased mechanism 100 resting at least partially within the fourth
hollow rod 94 and at least partially extending through the
length-adjustment hole 98 of the fourth hollow rod 94.

[0041] For example, the spring-biased mechanism 100 in the fourth hollow
rod 94, as illustrated in FIG. 4, may have a spring portion 102 having a
first end 104 and a second end 106 and a tab portion 108 attached to or
integral with the second end 106 of the spring portion 102. The first end
104 of the spring portion 102 may or may not be fixed to a surface within
the fourth hollow rod 94. The tab portion 108 may extend through the
length-adjustment hole 98 of the fourth hollow rod 94 and at least one of
the length-adjustment holes 96 of the third hollow rod 92 when these
length-adjustment holes 96,98 are aligned with each other. When the tab
portion 108 of the vessel retaining arm's spring-biased mechanism 100 is
pressed inward toward the spring portion 102 thereof, the fourth hollow
rod 94 may be slid toward or away from the handrail 22 of the apparatus
10 until another of the length-adjustment holes 96 of the third hollow
rod 92 aligns with the length adjustment hole 98 of the fourth hollow rod
94, allowing the tab portion 108 to spring out through the aligned
length-adjustment holes 96,98. In alternative embodiments, not shown
herein, there may be alignable length-adjustment holes on two opposing
sides of the third hollow rod 92 and/or the fourth hollow rod 94 and
there may be tab portions 108 on each end 104,106 of the spring portion
102, such that squeezing both tab portions 108 toward the spring portion
102 is required to adjust the length of the vessel retaining arm 24.

[0042] The vessel retaining arm 24 may also comprise a covering portion
110 configured to attach to or be integrally formed with a portion of the
fourth hollow rod 94 positioned outward of the third hollow rod 92. The
covering portion 110 may also be hollow and may comprise a cross-section
large enough to allow the covering portion 110 to slide over the third
hollow rod 92 when the fourth hollow rod 94 is slid into the third hollow
rod 92, as illustrated in FIG. 4. In some embodiments of the invention,
the covering portion 110 may be made of a plastic, rubber, or other
water-resistant material, thereby protecting the vessel retaining arm 24
from water damage and protecting the water vessel 18 from being scraped
by the vessel retaining arm 24. Specifically, the covering portion 110
may be configured to extend into the body of water 14 and assist in
trapping the water vessel 18 between the vessel retaining arm 24 and the
dock 12. In an alternative embodiment of the invention in which the
fourth hollow rod 94 is pivotally attached to the handrail 22, the
covering portion 110 may be attached to or formed integrally with the
third hollow rod 92.

[0043] The apparatus 10 may be reconfigurable between a folded
configuration, as illustrated in FIG. 6, and a fully deployed
configuration, as illustrated in FIGS. 1-2 and 5. When the apparatus 10
is in its folded configuration, the support structure 20, the handrail
22, and the vessel retaining arm 24 may each rest substantially parallel
with each other, as illustrated in FIG. 6, with the handrail 22 in its
folded configuration relative to the support structure 20 and the vessel
retaining arm 24 in its folded configuration relative to the handrail 22.
When the apparatus 10 is in its fully deployed configuration, as
illustrated in FIGS. 1-2 and 5, the handrail 22 extends outward over the
body of water 14 to rest substantially perpendicular relative to both the
support structure 20 and to the vessel retaining arm 24, with the
handrail 22 in its unfolded configuration relative to the support
structure 20 and the vessel retaining arm 24 in its unfolded
configuration relative to the handrail 22.

[0044] In use, a user may attach the apparatus 10 to an edge of any dock
12 at its base 30, as illustrated in FIGS. 1, 5, and 6. For example, the
first base portion 52 may be attached directly to a top surface of the
dock 12 and/or the second base portion 54 may be attached directly to a
side surface of the dock 12. The user 16 may also mechanically adjust the
lengths or extended lengths of the handrail 22 and of the vessel
retaining arm 24 when the apparatus 10 is in the fully-deployed
configuration, in the folded configuration, or somewhere between the
folded and the fully-deployed configuration. For example, the user 16 may
actuate the spring-biased mechanisms 74,100, pressing the one or two tab
portions 82,108 toward the spring portions 76,102, as described above, to
allow the first and second hollow rods 60,62 and/or the third and fourth
hollow rods 92,94 to slide relative to each other by a desired amount.

[0045] In particular, a length of the handrail 22 may be adjusted in a
direction away from (longer) or closer to (shorter) the support structure
20 of the apparatus 10 in the fully-deployed configuration, as desired,
depending on the size of the water vessel 18 over which the handrail 22
is intended to extend. For example, the length of the handrail 22 may be
set to a size which will trap the water vessel 18 between the vessel
retaining arm 24 and the dock 12, so that the water vessel 18 can not
pass therethrough. Furthermore, the vessel retaining arm 24 may extend
away from (longer) or toward (shorter) the handrail 22 of the apparatus
10 in the fully-deployed configuration, as desired, depending on the
level of the water 14 relative to the dock 12.

[0046] To reconfigure the apparatus 10 from the fully-deployed
configuration, as illustrated in FIGS. 1 and 5, into the folded
configuration, as illustrated in FIG. 6, the user 16 may first unlock the
handrail 22. Specifically, the user 16 may remove the locking pin 44 from
the locking hole 56 formed through the locking mechanism 34. Then the
user 16 may lift or pivot the handrail 22 toward the support structure
20. This may cause the vessel retaining arm 24 to also pivot relative to
the handrail 22. Additionally or alternatively, the vessel retaining arm
24 may have a locking mechanism (not shown) which will need to be
unlocked before it can pivot. In some embodiments of the invention, the
handrail 22 may be prevented from pivoting any further by the rigid strap
48. When the handrail 22 contacts the rigid strap 48, at least some of
the locking holes 40,58 of the support rail(s) 26,28 and the handrail 22
may be aligned. Then the user may insert the locking pin 44, previously
removed from the locking mechanism 34, through the locking holes 40,58 of
the support rail(s) 26,28 and the handrail 22, thereby locking the
handrail 22 in the folded configuration.

[0047] To reconfigure the apparatus 10 from the folded configuration, as
illustrated in FIG. 6, into the fully-deployed configuration, as
illustrated in FIGS. 1 and 5, the user 116 may first unlock the handrail
22 from the support rail(s) 26,28. Specifically, the locking pin 44 may
be removed from the locking holes 40,58 of the support rail(s) 26,28 and
the handrail 22. Then the user 16 may pivot the handrail 22 away from the
support rail(s) 26,28 toward the locking mechanism 34. The locking
mechanism 34 may be configured to prevent further pivoting of the
handrail 22 once the handrail 22 is substantially perpendicular to the
support rail(s) 26,28. In this position, the locking holes 58 of the
handrail 22 may be aligned with the locking hole(s) 56 of the locking
mechanism 34. Then the user 16 may insert the locking pin 44 previously
removed from the support rail(s) 26,28 through the locking holes 56,58 of
the locking mechanism 34 and the handrail 22.

[0048] To use the apparatus 10 to get into the water vessel 18, the user
16 may first pivot the handrail 22 into its unfolded configuration, then
place the water vessel 18 into the body of water 14 between the vessel
retaining arm 24 and the dock 12, such that the handrail 22 extends over
the water vessel 18 in a direction perpendicular to a length of the water
vessel 18, as illustrated in FIG. 1. The user 16 may then grasp the
support structure 20, the handrail 22, and/or the vessel retaining arm 24
while lowering themselves into the water vessel 18.

[0049] The user 16 may then maneuver the water vessel 18 away from the
dock 12 and then later return and maneuver the water vessel 18 toward the
dock. When the user 16 returns to the dock 12, they may position the
water vessel 18 between the vessel retaining arm 24 and the dock 12. Then
the user 16 may grasp the support structure 20, the handrail 22, and/or
the vessel retaining arm 24 to stabilize themselves as they stand in the
water vessel 18 and then step onto the dock 12. Once the user 16 is on
the dock 12, they may pivot the handrail 22 and vessel retaining arm 24
back to the folded configuration and then use the locking pin 44, as
described above, to retain the apparatus 10 in the folded configuration.

[0050] The flow chart of FIG. 8 depicts the steps of an exemplary method
800 of getting into and out of the water vessel 18 using the apparatus 10
in more detail. In some alternative implementations, the functions noted
in the various blocks may occur out of the order depicted in FIG. 8. For
example, two blocks shown in succession in FIG. 8 may in fact be executed
substantially concurrently, or the blocks may sometimes be executed in
the reverse order depending upon the functionality involved.

[0051] The method 800 of using the apparatus 10 attached to the dock 12 to
get into and out of the water vessel 18 may comprise the steps of
unlocking the handrail 22 from the support structure 20, as depicted in
block 802, then pivoting the handrail 22 from its folded configuration,
as illustrated in FIG. 6, to its unfolded configuration, as illustrated
in FIG. 5, such that the handrail 22 extends over the water vessel 18, as
depicted in block 804 and illustrated in FIGS. 1-2. Next, the method 800
may comprise the steps of locking the handrail 22 to the locking
mechanism 34 in the fully-deployed configuration, as depicted in block
806, and/or actuating the spring-biased mechanism 74 of the handrail 22
such that the handrail 22 may be reconfigured to span a greater or a
shorter distance relative to the dock 12, as depicted in block 808.
Additionally, the method 800 may comprise a step of actuating the
spring-biased mechanism 100 of the vessel retaining arm 24 such that the
vessel retaining arm 24 may be reconfigured to span a greater or a
shorter distance relative to the handrail 22, as depicted in block 810.

[0052] Then, the method 800 may comprise the steps of grasping the support
structure 20, the handrail 22, and/or the vessel retaining arm 24 while
simultaneously lowering one's self into the water vessel 18, as depicted
in block 812, and maneuvering the water vessel 18 away from the dock 12
and the apparatus 10, as depicted in block 814. The method 800 may
further comprise the step of maneuvering the water vessel 18 back toward
the dock 12 and the apparatus 10 until the water vessel 18 is positioned
beneath the handrail 22 and between the vessel retaining arm 24 and the
dock 12, as depicted in block 816. Then, the method 800 may comprise the
steps of grasping the support structure 20, the handrail 22, and/or the
vessel retaining arm 24 while simultaneously pulling one's self out of
the water apparatus 18, as depicted in block 818, and pivoting the
handrail 22 back into the folded configuration, as depicted in block 820
and illustrated in FIG. 6. Finally, the method 800 may comprise the step
of locking the handrail 22 relative to the support structure 20 in the
folded configuration, as depicted in block 822 and illustrated in FIG. 6.

[0053] Although the invention has been described with reference to the
preferred embodiment illustrated in the attached drawing figures, it is
noted that equivalents may be employed and substitutions made herein
without departing from the scope of the invention as recited in the
claims. For example, in some alternative embodiments of the invention,
the spring-biased mechanisms 74,100 may be omitted and additional locking
pins (not shown) may be inserted through aligned ones of the
length-adjustment holes 70,72,96,98 to prevent sliding between the first
and second hollow rails 60,62 and/or the third and fourth hollow rails
92,94.
